Direct Injection of Ultrashort Electron Bunches Into a Solid Material Using Terahertz-Driven Electron Field Emission

Research output: Chapter in Book/Report/Conference proceedingBook chapterResearchpeer-review

Abstract

We present here how terahertz (THz)-driven electron field emission from gold antennas can be directly injected into a solid material without any intermediate vacuum path. Simulations show that an ultrashort sub-ps driving THz laser pulse results in even shorter sub-ps electron bunches with up to 420 eV energies under vacuum conditions. An experiment shows that these electron bunches can be formed and accelerated directly inside the bulk of a solid under standard laboratory conditions (SLC). This is observed via the interaction of the electrons with scintillating molecules, which are placed inside the solid. Our result is a key step towards building a novel platform for femtochemistry driven by ultrashort electron bunches.
